Rotating cleaning brush

Abstract

A rotating cleaning brush includes a connection pin to be clamped in a chuck of a machine for rotatingly driving the cleaning brush about its longitudinal axis. The cleaning brush includes a bristle carrier including a plurality of openings. The bristle carrier includes a first bristle bundle and a second bristle bundle being adjacent along the longitudinal axis. The first bristle bundle is located closer to the first end region of the cleaning brush than the second bristle bundle. Each of the bristle bundles includes a plurality of bristles and is located in one of the openings. The bristles of the first bristle bundle are designed to bend towards the longitudinal axis and then run parallel to the longitudinal axis so as to overlap the opening in which the second bristle bundle is arranged.

I claim: 
     
       1. A cleaning brush configured to be rotated, the cleaning brush comprising:
 a longitudinal axis; 
 a first end region; 
 a second end region, the first end region and the second end region being spaced apart along the longitudinal axis; 
 a connection pin arranged in the first end region, the connection pin being configured to be clamped in a chuck of a machine for rotatingly driving the cleaning brush about the longitudinal axis; and 
 a bristle carrier comprising,
 a shell surface and a top surface, the top surface being located in the second end region and having a rounded shape, 
 a plurality of openings arranged in the shell surface, and 
 a first bristle bundle and a second bristle bundle arranged to be adjacent to each other along the longitudinal axis, the first bristle bundle being located closer to the first end region than the second bristle bundle, each of the first bristle bundle and the second bristle bundle comprising a plurality of bristles and being arranged in one of the plurality of openings, 
 wherein, 
 the bristles of the first bristle bundle bend towards the longitudinal axis and then run parallel to the longitudinal axis so as to overlap the opening in which the second bristle bundle is arranged. 
 
 
     
     
       2. The cleaning brush of  claim 1 , wherein the bristle carrier is designed to have a cylindrical shape. 
     
     
       3. The cleaning brush of  claim 1 , wherein the bristle carrier is designed to have a conical shape. 
     
     
       4. The cleaning brush of  claim 1 , wherein the bristles have an identical length. 
     
     
       5. The cleaning brush of  claim 1 , wherein the bristles include free ends, the bristles being designed and arranged such that the free ends are located in one common plane. 
     
     
       6. The cleaning brush of  claim 1 , wherein the plurality of openings are arranged in the shell surface of the bristle carrier in an annular configuration. 
     
     
       7. The cleaning brush of  claim 1 , wherein the plurality of openings are arranged in the shell surface of the bristle carrier in a helical configuration. 
     
     
       8. The cleaning brush of  claim 1 , wherein each bristle includes at least two plastic fibers. 
     
     
       9. The cleaning brush of  claim 8 , wherein the bristles include free ends, the plastic fibers being designed such that they are spliced at the free ends. 
     
     
       10. The cleaning brush of  claim 1 , wherein the bristles have a curved shape. 
     
     
       11. The cleaning brush of  claim 1 , wherein the bristle bundles further comprise:
 a third bristle bundle arranged to be adjacent to the second bristle bundle along the longitudinal axis, the third bristle bundle being located closer to the second end region than the second bristle bundle, and 
 the bristles of the first bristle bundle bend towards the longitudinal axis and then run parallel to the longitudinal axis so as to overlap the opening in which the third bristle bundle is arranged. 
 
     
     
       12. The cleaning brush of  claim 11 , wherein the bristle bundles further comprise:
 a fourth bristle bundle arranged to be adjacent to the third bristle bundle along the longitudinal axis, the fourth bristle bundle being located closer to the second end region than the third bristle bundle, and 
 the bristles of the first bristle bundle bend towards the longitudinal axis and then run parallel to the longitudinal axis so as to overlap the opening in which the fourth bristle bundle is arranged. 
 
     
     
       13. The cleaning brush of  claim 1 , wherein the bristles of the first bristle bundle are designed to bend towards the longitudinal axis and then run parallel to the longitudinal axis so as to overlap at least three openings being arranged closer to the second end region. 
     
     
       14. The cleaning brush of  claim 1 , wherein the bristles of the first bristle bundle are designed to bend towards the longitudinal axis and then run parallel to the longitudinal axis so as to overlap at least four openings being arranged closer to the second end region.
